Problem with DDP4. Photos stuck in there.

Hi . A new member to the Canon world. Bought the Eos 800d . Practised on a fuji fine pix and the old Canon 350. Both set up to store in raw. Runing a windows 7 desk top and used the windows ac wizard to convert to jpg and save. no probs .

I know want too edit raw and move on . I have installed the soft ware , pictures show up and I can edit a picture but can not move from there. Click on save , go back and nothing happens apart from the same image as edited .

In my picture libery it just shows the microsoft broken pic image. In my files it just shows a date folder. Imposable to convert from raw - jpg. Microsoft shows various instructions ...change file name , done..no change.

Also tried useing another picture editor that I know is ok ...Gimp....just shows no images found that match your search.
